Galaxy S9 series reportedly experiences battery drain on Pie
Samsung has re-scheduled its planned roll-out of Android Pie for the Galaxy S9 series of devices to December 24, presumably as a goodwill gesture for users who have been waiting for a stable upgrade of this sort for a while now. However, reports from SamMobile suggest that the number of countries in which S9 and S9+ owners have received the upgrade notification are few and far between.
A writer for this outlet who claims that his S9+ has received the update has also noticed that its battery capacity is behaving differently compared to the same on Oreo. This correspondent noted that his own battery level suddenly dropped by 5% at one point. On the other hand, it is not unusual for devices running a new or updated ROM to have battery issues that iron out over time. The same writer also claimed that battery life appears to be better overall on Pie compared to Oreo.
This is not the only specific disappointment found on Pie for 2018 Samsung flagships. Earlier in the year, we reported that Adoptable Storage may be making a comeback to this OEM with Pie. This could have been a welcome move from the company, especially for owners of low fixed-storage SKUs. Unfortunately, correspondents from SamMobile and XDA have confirmed that this is not the case. They were unable to find it on their S9-line devices, or on Galaxy Note 9s running the official One UI beta based on Pie.
